MOTOR HEAD.

Application filed March 21, 1924.

To al! whom t may concern.'

lle it known that l, EvAnis'ro Annneo, a citizen of the United States,residing at San Antonio, in the county of Bexar and State of Texas, haveinvented a new and useful. hotor Head, of which the following is aspeciiication.

This invention relates to cylinder heads for combustion engines and theobject thereof is to so construct suc-h a head as to provide means forcontinuously cleansing the spark plugs whereby the lir'e of the plugs'is lengthened and its effectiveness increased, all short circuits andignition troubles at this point being eliminated.

Another object is to provide a cylinder head with walls built around theintake valves and equipped with an opening located directly in front ofthe spark plugs so that at every suction stroke of the engine the gasdrawn into the explosion chamber will shift straight through the. sparkplugl points whereby the points are washed at every operation thusproducing a continuous cleansing action on the plug.

lVith the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed may be made within thescope of what is claimed without departing from the spirit of theinvention.

In the accompanying drawings Figure l represents a bottom plan view oi?a portion of an engine cylinder head constructed in accordance with thisinvention.

Fig. 2 is a transverse section taken on the vline 2 2 of Fig. l, and

Fig. 3 is a longitudinal section taken on the line 3 3, Fig. l.

ln the embodiment illustrated, a cylinder head 1 is shown of the typeused on Ford cars and which is equipped with the usual water jacket 2,the inner wall of which forms a dome-shaped ceiling 3 for the head,

Serial No. 700,901.

This head l is equipped with the usual chambers 4 and 5 which lit overthe exhaust and intake valves G and 7 as is shown clearly in Fig. l. Thechamber 5 which houses the intake valve 7 is separated from chamber 4 bya wall 8 and from the chamber 10 which registers with the cylinder by awall 9, the latter following the radius ot the valve and cylinder butallowing Yfor a clearance of both as is shown clearly in Fig. l. Anopening l1 is formed between the walls 8 and 9 which opening is locateddirectly in front of the spark plug 12.

It is of course well known that a clean spark plug makes the motor sparkeasy when it is cold and this is insured by locating the points of theplug directly in the path of the gas sucked into the cylinder from theintake manifold through valve 7 and passage l1. Vhen the motor isrunning the spark plug is protected by a cool wash on every suction ofthe piston.

7hile this head is primarily intended for a Ford car motor, obviouslythe invention may be used in connection with any motor head that is,with any motor having a. detachable head. Any forni ot' spark plug maybe used in connection with this head.

What is claimed is A cylinder head having a combustion chamber therein,exhaust and intake valve housing chambers, a wallseparating saidchambers, a spark plug located adjacent the intake manifold chamber,said wall having an opening therein opposite the plug for the passage ofgas from the intake valve to the combustion chamber and in the path ofwhich the port-s of the point are located whereby each suction stroke otthc cugino cleauses the plug.

In testimony that I claim the 'foregoing as my own, I have heretoaffixed my signature in the presence of two witnesses.
